IMPROVEMENT IN- FIRE-POTS FOR STOVES.

Specification forming part of Letters Patent No. 42,835. dated May 24,1864.

To all whom it may concern:

Be it known that I, N. OSCAR BOND, of

v of Massachusetts, have invented a new and Improved Fire-Pot for Stovesor Furnaces; and 1 do hereby declare the following to be a full andexact description of the same, reference being had to the accompanyingdrawings, making part of this specification, in which Figure l is avertical section, at w a, of a Fig. 2 is a \ertical section thereof at yy. Fig. 3 is a lit rizontal section at z 2. Fig. 4 is a perspect' Weview of the fire-pot detached, on a smaller scale, a part of the outershell being broken away.

Similar letters of refeienee indicate corresponding parts in the severalfigures.

My invention is an improvement in what are known as base-heating stovesor furnaces, or thesein which the products of combustion are carrieddown through diving or descending flues, so as to radiate heat at thelower part of the stove.

The present improvement consists in a peculiar construction of fire-pot,which combines the qualities of efficiency, durability, and cheapness toa greater degree than those in common use.

In order that others skilled in the art to which my invention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe its construction and operation.

The ashpit A, hearth B, grate G, combuslion-chamber D, fire-door E,descending flues F, base-flues F, and discharge-flue F may beconstructed and arranged in any suitable manner, and require no specificdescription.

My improved fire-pot is, by preference, constructed in the followingmanner:

G represents a cylinder formed in one piece of cast-iron, or othersuitable material, with flanges H H above and below, the lower flange, H,bein g formed with apertures 11/, for the passage of air, ashereinafter explained.

I isa casing of sheetiron, fitted and secured tightly over the flanges HH, so as to inclose an annular chamber, J, around the cylinder G.

K represents a pipe com munieatin g with the upper part of theannularschamber J, for the purpose of conveying heated air there' fromand discharging it within the apart ment in which the stove is placed,or any other which it may be desired to warm.

The air may be supplied to the interior of the chamber J throughpassages L L in the base of the stove, communicating with the aperturesh, or in any other suitable manner.

The capacity of the chamber J is determined by the width of the flangesH ll. By

making this chamber perfectly air-tight, with the exception of theopenings b fore described, the cylinder may be made complete in itselfand applicable to any of the common forms of base-heating parlorcoalstoves without interfering with their modes of distributing the heatrising from the top of the fire-pot.

The Wall of the cylinder G, within the chamber J, may be coated with anypreparation or material to lessen the intensity and temper the effect ofthe heat upon the air circulating through chamber J.

Having thus described my invention, the following is what I claim as newand desire to secure by Letters Patent:

As a new article of manufacture, the improved fire-pot hereinbeforedescribed, the said fire-pot consisting of the cast-iron flangedcylinder G H H, sheet-iron casing I, inlets h, and outlet K, all asrepresented.
